Solution Steps

Step 1: Locate structure number 10

Number 10 is located on the inside wall of the right atrium. It appears to be a muscular ridge.

Step 2: Identify the structure

Muscular ridges on the inner wall of the atria are called pectinate muscles.

Final Answer: The correct answer is G. Pectinate muscle.

Consider a situation in which a flask is half-filled with liquid water at room temperature. The partially filled flask is then sealed and given time to reach equilibrium. Which of the following statements are true? [Select all that apply.] Once the flask reaches equilibrium the rate at which water molecules move from the liquid to the gas phase is equal to the rate at which water molecules move, from the gas to the liquid phase. If given enough time, the water will evaporate completely. After the flask reaches equilibrium, there will no longer be any movement of individual water molecules from the gas phase into the liquid phase. After the flask reaches equilibrium, there will no longer be any movement of individual water molecules from the liquid phase into the gas phase. The rate of condensation decreases as the flask approaches equilibrium. The rate of condensation increases as the flask approaches equilibrium. The vapor pressure of the water is the total pressure in the flask after it reaches equilibrium. The vapor pressure of the water is the partial pressure of water (Pwater) in the flask after it reaches equilibrium.
